Background: Breast cancer is one of the most common cancers and a major public health problem in developing countries. However, early detection and treatment may be achieved by breast self-examination (BSE). Despite the importance of BSE in reducing the incidence of breast cancer and esultant deaths, the disease continues to be the most common cause of cancer death among women in Iran.This study aimed to determine the effects of self-care education on performance of BSE among women referring to health centers in our country. Materials and Methods: This quasi-experimental interventional study with pretest/posttest control group design was conducted on 168 women referred to health centers. The data were collected using a validated researcher-made questionnaire including demographic variables and trans-theoretical model constructs as well as a checklist assessing BSE behavior. The instruments were administered to groups with and without self-care education before, a week after, and 10 weeks after the intervention. Then, the data were entered into the SPSS statistical software (version 19) and analyzed using independent sample t-tests, paired sample t-test, repeated measures ANOVA, Chi-square, and Friedman tests (p<0.05). Results: The results showed an increase in the intervention group's mean scores of trans-theoretical model constructs (stages of change, self-efficacy, decisional balance, and processes of change) and BSE behavior compared to the control group (p<0.001). Conclusion: The study confirmed the effectiveness of aneducational intervention based ona trans-theoretical model in performing BSE. Therefore, designing educational interventions based on this model is recommended to improve women's health and reduce deaths due to breast cancer.

This paper proposes a single control strategy to solve the problem of trans-media vehicle difficult control. The proposed control strategy is just to control the vehicle's air navigation, but not to control the underwater navigation. The hydrodynamic model of a vehicle when entering water obliquely at low speed has been founded to analyze the motion characteristics. Two methods have been used to simulate the vehicle entering water in the same condition: numerical simulation method and theoretical model solving method. And the results of the two methods can validate the hydrodynamic model founded in this paper. The entering water motion in the conditions of different velocity, different angle, and different attack angle has been simulated by this hydrodynamic model and the simulation has been analyzed. And the change rule of the vehicle's gestures and position when entering water has been obtained by analysis. This entering water rule will guide the follow-up of a series of research, such as the underwater navigation, the exiting water process and so on.

In this study, a linearized super-cavitation theory was applied in order to analyse the performance of the 2-dimensional foils. For flat plate with non-thickness, the numerical results correlated very well with Nishiyama's theoretical results for closed cavitation model. For plano-convex section, the numerical results correlated very well with Wade's experimental data. The new lifting surface procedure, developed and validated in this study, is generally considered applicable to the performance analyses of the super-cavitating propeller and trans-cavitating propeller.

The fiber morphologies of the textiles from the burials of the Seip group of Ohio Hopewell (ca. 100 B.C. to A.D. 500)mounds were examined using light and scanning electron microscopy. A theoretical model was proposed which delineates the rate of morphological change in fibers through time and the cultural activities which occur during the life of a textile element. The Seip textiles were categorized according to their visual and structural characteristics. The microscopic examination of the Seip textiles yielded the evidence of animal hair fibers and bast fibers. The animal hair fibers of the seip textiles were identified as the hair of rabbit or hare. The bast fibers of the Seip textiles exhibited variation in morphological features such as the degree of bundle separation and the presence of transverse striations, fibrillations, or trans-verse cracks.

The purpose of this study was to analyze variables associated with smoking and selected health behaviors. This study targeted adult men and women over 20 of age. The sample population was drawn from the national sample, and the samples were chosen from the telephone book. A total of 1,500 cases were collected through a telephone based interview survey. As a tool for this study, a structured questionnaire was developed. the variables included self-perceived health status, and selected 7 health behaviors; smoking behavior, physical activities, eating habit, weight control, alcohol consumption, stress management, and cancer exam. The healthy life practice actions of Trans-theoretical model have been classified into five stages. Smokers were more likely than non-smokers to positive attitudes toward smoking and the impact of smoking in this study. This means that smokers's awareness toward the impact of smoking is very week. Smoking behavior was significantly related to other health related behaviors based on the correlation analysis. However, gender, engaging in regular physical activities, moderate consumption of alcoholic beverages, and receiving a cancer examination were the variables that can explain and predict a person's stages of adopting a non-smoking behavior. Self perceived health status was closely related to other health behaviors. Gender, age, and monthly household income were important demographic variables that have significant relationship with the self-perceived health status. Among the health behaviors, regular physical activities and weight control were significant predictable variables. Similar results have been found in the National health and Nutrition examination survey in Korea. As a result of this study, it was found that among the selected health behaviors, engaging in physical activity was an important variable to increase positive sense of health and non-smoking behaviors. Educational and policy level input is needed to increase awareness and provide chances to participate in fitness activities. To those who maintain exercise, the environmental support and diffusion of knowledge information and education data should be strengthened. To change attitudes toward smoking, more in-dept awareness campaign and education should be provided according to people's different behavioral status. In addition, not only diffusing health education data and delivering knowledge information through related programs, but also environmental support system that helps an individual maintain his/her action is required. Such a support system means settlement of the health enhancement base of school, workplace and community should be carried out, and the policy level support and regular programs should be provided and spread to the unit of community.

Purpose: This study was to predict the stage of exercise behavior change in undergraduate students and to identify the factors affecting exercise behavior change by using the trans theoretical Model. Method: The subjects were 193 undergraduate students at K and D university in D city. Data were collected by questionnaire surveys using convenience sampling and analyzed by SPSS 12.0 program. Results: 77.7% of 193 nursing students do not exercise or they exercise irregularly. Exercise self-efficacy score and exercise benefits score were decreased with advancing exercise stage, on the other hand exercise barriers score and the process of exercise behavior change score were increased. In addition to this, the results revealed that stage of exercise behavior was significantly correlated with the process of exercise behavior change, exercise benefits, exercise barriers and exercise self-efficacy. Conclusion: These results suggested that the process of exercise behavior change, exercise decisional balance and exercise self-efficacy can be potential affecting factors for the stages of behavior change in university students. Therefore, these findings give useful information for educating nurse to construct nursing service programs focused on the stage of behavior change.

본 연구는 각 미디어의 리얼리티와 오디션 프로그램의 상품성 등 몇 가지 측면에서 실존주의를 이론 모델로 오디션 프로그램의 리얼리티가 왜곡되는 상황에 대해 살펴보고자 했다. 실존주의의 제1원리 '주관성'에 따르면 사람들은 자유의지에 따른 행동을 통해 자신의 본질을 만든 이론적 관점에서 알 수 있듯이 제작 과정에서 캐릭터 메이킹과 스토리텔링을 통해 인물의 이미지를 만들고, 방송 분량 증감을 통해 마지막으로 결성된 단체 인물의 포지션 균형을 이룬다. 연구 결과에 의하면 제작진의 주관적인 개입으로 인해 비본질적인 모습을 대외적으로 드러냄으로써 본질적인 왜곡을 초래한다는 것을 알 수 있다. 상품화 사회에서 무조건 이익만 추구하면 커뮤니케이션의 윤리성과 괴리가 생기고, 리얼리티와 이익의 균형을 어떻게 맞출 수 있느냐가 여전히 현재 오디션 프로그램의 주요 문제이다.

Purpose: This study was done to identify the distribution and related factors for stage of change for wearing hearing protection devices (HPDs) by workers in environments with high noise. Predictors of Use of Hearing Protection Model and Trans-theoretical Model were tested. Methods: The participants were 755 workers from 20 noisy work places in Busan and Gyeongnam. Data were collected from January to April 2008 using self-administered questionnaires, and analyzed using multiple logistic regression. Results: There were significant differences in social mode (OR=1.35, 95% CI: 1.06-1.73) between precontemplation/contemplation and preparation stage, in males (OR=2.36, 95% CI: 1.24-4.51), workers with high school education or less (OR=1.39, 95% CI: 1.28-2.78), shift workers (OR=1.50, 95% CI: 1.02-2.21), workers who previously worked in noisy places (OR=1.39, 95% CI: 1.20-2.34), and workers who had previous hearing examinations (OR=1.89, 95% CI: 1.25-2.85), in the social model (OR=1.59, 95% CI: 1.42-1.78), and self-efficacy (OR=1.05, 95% CI: 1.02-1.08) between workers in preparation and action stages, in length of time working in noisy work places (OR=2.26, 95% CI: 1.17-4.39), social model (OR=1.66, 95% CI: 1.33-2.08), and perceived benefit (OR=0.95, 95% CI: 0.93-0.97) between action and maintenance stage. Conclusion: Social model was a common factor showing differences between two adjacent stages for wearing HPDs. The results provide data for developing programs to encourage workers to wear HPDs and application of these programs in work settings.
